Every card carries one of these. They last about twenty seconds, there is no way to lose, and they all end on the birthday cake with the person’s name on it. Pick one in the editor, under Play, and change it whenever you like: the card keeps your message.

Each game has its own page, with what happens on the card and what to write in it: see birthday cards by theme.

How they are made

Each game is drawn and coded by hand for the phone screen, with its own music and real recorded sounds. A new game arrives most weeks, often from something in the news that week.
